Benzenesulfonamides compositions for treatment of malignant pleural effusions

Abstract

The present disclosure provides a novel pharmaceutical composition for treating a malignant pleural effusion (MPE), including a benzenesulfonamide derivative and a pharmaceutically acceptable excipient. The present disclosure further provides a method for treating MPE by using the pharmaceutical composition.

What is claimed is: 
     
       1. A method for treating a malignant pleural effusion (MPE), comprising
 administering a pharmaceutical composition to a subject in need thereof, wherein the pharmaceutical composition comprises a benzenesulfonamide derivative represented by a compound of formula (I): 
 
       
         
           
           
               
               
           
         
         wherein R 1  to R 6  are each independently selected from the group consisting of H, C1-C6 linear or branched alkyl, C4-C6 linear or branched alkoxy, amino, halo, halo-substituted C1-C6 linear or branched alkyl, and sulfonamide group; and 
         administering at least one additional MPE therapy, wherein the at least one additional MPE therapy is chest drainage. 
       
     
     
       2. The method according to  claim 1 , wherein the benzenesulfonamide derivative in the pharmaceutical composition is administered to the subject in a therapeutically effective amount of from about 1000 mg to about 1800 mg per day. 
     
     
       3. The method according to  claim 1 , wherein the pharmaceutical composition is administered to the subject intratumorally, intravenously, subcutaneously, intradermally, orally, intrathecally, intraperitoneally, intranasally, intramuscularly, intrapleurally, or through nebulization. 
     
     
       4. The method according to  claim 1 , wherein the subject is suffering from cancer. 
     
     
       5. The method according to  claim 4 , wherein the cancer is at least one selected from the group consisting of lung cancer, breast cancer, lymphoma, leukemia, and mesothelioma. 
     
     
       6. The method according to  claim 1 , wherein the additional MPE therapy is further consists of video-assisted thoracic surgery (VATS), intrathoracic administration, pleural fixation, whole body chemotherapy, radiotherapy, or thermal therapy. 
     
     
       7. The method according to  claim 1 , wherein the compound of formula (I) is selected from the group consisting of p-toluenesulfonamide, o-toluenesulfonamide, N-ethyl-p-toluene sulfonamide, N-ethyl-o-toluene sulfonamide, N-cyclohexyl-p-toluene sulfonamide and a combination thereof. 
     
     
       8. The method according to  claim 1 , wherein the benzenesulfonamide derivative is present in the pharmaceutical composition in an amount ranging from about 10% to about 50% by weight. 
     
     
       9. The method according to  claim 8 , wherein the pharmaceutical composition further comprises at least one of 10%-40% by weight of PEG-400, 5%40% by weight of 1,2-propylene glycol, 1%-5% by weight of sebacic acid, 10%-20% by weight of 2-ethyl-1,3-hexanediol, 0%-10% by weight of dimethyl sulfoxide and 0%-10% by weight of ethanol.
